OPERATING MECHANISM FOR wHIsTLns.

Specification of Letters Patent. Patented J 311.13, 1920.

Application filed April 9, 1919. Serial No. 288,697.

To all whom it may concern:

Be it known that I. DUANE P. FULLER, a citizen of the United States,residing at Carlisle, in the county of Grays Harbor and State ofWashington, have invented certain new and useful Improvements inOperating Mechanism for Whistles, of which the following is aspecification.

This invention relates to an improvement in an operating mechanism forwhistles, whereby the whistle may be operated from a remote point with acertainty of control and operation substantially equal to that of ashort whistle cord.

It is particularly desirable in some operations, as in logging, thatmeans be provided to permit the remote workman to signal to the engineerof the stationary engine employed as to what action is desired. This isusually done by providing an ordinary type of whistle, or other manuallyoperable alarm. on or adjacent the engine,-with the operating meansthereof extending a considerable distance. It has heretofore beenproposed to connect a whistle cord to a spring post. and also to connectthe operating cord to said post. The pull on the operating cord isdesigned to move the upper end of the post to thereby actuate thewhistle cord and thereby sound a whistle. This can be readilyaccomplished by the operating cord extending in line with the whistlecord. but even then the vibration of the post will materially interferewith, if not preclude.a series of whistle signals in rapid succession,as may be necessary. Furthermore unless the operating cord extends in adirect line with the whistle cord. as for example if it should extend atright angles thereto, the device described would be practicallyinoperative.

The present invention overcomes these objectio s by providing means toeliminate the vib ation of the post. and to permit the operating cord toextend in any direction, from, and with the respect to, the whistlecord.

Tn the drawings Figure 1 is a side elevation illustrating the invention.Fig. 2 is a side elevation of the upper en of the movable post.

Fig. 3 is a plan of the same.

Fig. 4 is a side elevation. and Fig. 5 a front elevation of theoperating cord guidlng means. I

For-convenience and illustration the im- 'proved alarm is here shown asa whistle 2,

mounted upon an ordinary type of donkey or other engine 1, suchillustration of course indicating any type of manually operable signaland any power plant.

Whistle 2 is of any usual or preferred type, here shown as a steamwhistle, normally held closed in any appropriate manner and opened foralarm sounding purposes'in the operation of lever 3.

A post 10 is pivotally mounted at 11, on the engine base, or othersupport adjacent the engine. The upper end of the post 10 is providedwith a casting having a pair of horizontally disposed spaced parallelguide rollers 5 notatively mounted in such casting.

A second post 13 .is rigidly mounted on the engine, base or othersupport, and is provided at the upper end with a bracket carryingvertically arranged spaced parallel guide rollers 9.

The whistle cord 4 is connected at one end to the whistle lever 3,passes over one of the rollers5 from above. and downwardly to a point inadvance of the post 10. and terminally fixed at 6. The operating cord 8is terminally wound about a drum as 7, mounted upon a support betweenthe posts 10 and 13. The drum is provided with an operating handlewhereby the cord 8 may be wound thereon when not required for use andmay have an ordinary dog and ratchet to prevent unwinding of the drumafter a suflicient le gth of cord 8 has been unwound from the drum toextend such cord to the point required. The cord 8 extends from the drumforwardly and over the remaining roller 5 from beneath. being thenpassed between the rollers 9, and led therefrom in any desireddirection.

A pull on the cord 8. no matter in what direction it may exte d from thepost 13. will move the up er end of the post 10 from the whistle.pulling upon lever 3 through the whistle cord 4 and soundin the whistle.Upon release of the pull on cord 8 the spring of the whistle returns thepost 10 to normal position. through the whistle cord. the dependingportion of such cord preventing any vibratory movement of such post. Thewhistle may be thus sounded in ouick succession b proper operation oftheoord 8. substantiall the same as it the whistle cord was beingdirectly operated.

What is claimed, is:-

1. Means for transmitting motion comprising a pivoted post, a cordfastened at one end and having a sliding cooperation with the post, theother end of the cord extending away from said post, and an operating'cord having a fixed terminal and an operating terminal, said operatingcord having sliding connection with the post between its terminals.

2. Means for transmitting motion comprising a pivoted post, a cordhaving a sliding cooperation with the post, one terminal of the cordbeing fixed and the other terminal extending from the post and anoperating cord having a fixed terminal and an operating terminal, saidoperating cord having sliding connection With the post between itsterminals, and a drum about which the operating cord may be Wound toserve as the fixed terminal of such cord.

In testimony whereof I afiix my signature.

DUANE P. FULLER.
